AbstractThe increasing dimensionality of data in the modern computing age presents new challenges and opportunities to the field of signal and data processing.  One the one hand, processing these data requires new software and hardware solutions, on the other hand, the high-dimensional settings allow one to use powerful asymptotic methods from probability theory and statistical physics to obtain precise characterizations and develop new algorithmic approaches.

Here I will present some of the results obtained through these methods for two sets of problems: (i) reconstructing a signal from a minimal number of measurements in a variety of situations, including for instance phase retrieval and (ii) analyzing the performances of neural networks and their ability to avoid overfitting. I will also discuss some practical implementations of these ideas for both problems in the context of optics in random media and optical computing.
